As for a background, you can use any *.jpg file you want, in the format 800x600 and copy it in the skin Editor Folder.
for your convenience, here is one. Right click annd save as, then save it in the skin editor folder.

I figured it out. Had taken a screen-shot of RR + inifiles + bgdir, uploaded it to this post, then studied it one last time before posting... noticed the bgdir was named "backrounds" rather than "backgrounds". lol
